GTECÂŽ SYSTEMS FOR HEALTHCARE

SYSTEMS FOR HEALTHCARE GTEC Plasterboard Systems have been used extensively in major healthcare projects across the UK and Ireland as fast and effective solutions to healthcare construction. The GTEC Boards and GTEC Systems have been developed to meet and exceed the full range of extraordinary demands placed on hospital and healthcare buildings.

EXTRAORDINARY DEMANDS ACOUSTICS:

The acoustic demands on partitions in Healthcare buildings are extreme; from ensuring consultation room privacy and operation suite concentration, to dealing with emergency vehicle sirens and the intensity of A&E departments. While layout can ease noise risk, GTEC Systems allow for flexible design with extremely high levels of sound insulation from space to space. The partition performance ensures that a superior healing environment is achieved. GTEC Pregybel ceilings also help to control noise levels through acoustic absorption.

FIRE:

Multi-storey constructions containing bed-bound patients, large public areas, multiple service entrances and numerous circulation routes, place a high fire resistance demand on any project. GTEC Partitions and GTEC Ceilings provide a simple design with high levels of fire resistance and robust detailing for design flexibility. GTEC Shaftwall and GTEC Encasement Fire Protection solutions offer specialist passive fire protection to lifts, shafts and structural steel.

IMPACT:

Hospitals are dynamic, highly trafficked, public environments where walls are subject to constant impact from staff, visitors and hospital equipment. GTEC LaDura, a unique and exceptionally strong plasterboard, achieves severe duty ratings with the minimum of boarding. Plus, it provides high levels of fixing resistance for crash rails, skirting, services and fixtures.

HYGIENE:

Easy to clean surfaces are vital for good healthcare environments which need frequent washing, and are dependent on excellent hygiene. GTEC Finishing solutions combined with GTEC Partition and Lining systems offer smooth, easy to joint and repairable surfaces which are easier to clean. GTEC Megadeco Board requires no pre-sealing for even faster finishing.

GTEC® SYSTEMS FOR EDUCATION

SYSTEMS FOR EDUCATION GTEC Plasterboard Systems have been adopted in hundreds of school, academy, college and university projects across the UK and Ireland to efficiently meet the needs of education construction. The range of GTEC Board and GTEC Systems suit the full scope of extraordinary demands placed on education buildings.

EXTRAORDINARY DEMANDS ACOUSTICS:

From music and sports noise to examination room silence, Education buildings place extreme acoustic demands on specification. The isolation and control of ambient noise from space to space is vital, as is good speech clarity in open spaces, along with controlled reverberation. While layout design can reduce noise risk, GTEC Systems’ high level of sound insulation allows design flexibility from space to space. GTEC Pregybel ceilings offer acoustic absorption and echo control, improving speech clarity and reducing noise distractions.

FIRE:

“Each year around 1 in 20 schools experiences a fire and nearly 60% of school fires are started deliberately.” BB100 Large circulation areas, multi-storey construction and broad types of use from science labs to sports halls place a high fire resistance need on any Education project. GTEC Partitions and GTEC Ceilings achieve high levels of fire resistance with uncomplicated, robust and proven detailing for design flexibility. GTEC Shaftwall and GTEC Encasement Fire Protection solutions offer specialist passive fire protection to lifts, shafts and structural steel.

IMPACT:

Education buildings face some of the most intense usage. With high levels of student movement, a wide variety of activities taking place and the chance of misuse, careful specification is needed to reduce maintenance and repairs. GTEC LaDura Board is exceptionally strong and achieves severe duty ratings with the minimum of boarding. It offers excellent impact performance for corridors and high levels of fixing resistance for fixtures and fittings.

DESIGN:

An innovative design can transform the learning experience of students, enhancing their performance, motivation, behaviour and engagement. Ideal for the most ambitious projects, GTEC Systems are flexible, high performance and easy to install, providing quick construction. GTEC LaDura, Aqua Board and Megadeco take plasterboard systems to new areas replacing slower, less flexible, wet construction methods.

GTEC® SYSTEMS FOR RESIDENTIAL

SYSTEMS FOR RESIDENTIAL GTEC Plasterboard Systems have been used across the UK and Ireland to successfully build or renovate thousands of housing, apartment and hotel projects. The diverse range of GTEC Board and GTEC Systems features solutions ideal for the construction of homes and other residential buildings.

EXTRAORDINARY DEMANDS ACOUSTICS:

Busy lifestyles, close neighbours and urban noise can all combine to affect the quality of home life. Party walls, party floors, partitions and ceilings all require special attention to reduce noise issues. GTEC Systems are tested to achieve extremely high levels of sound insulation. They meet Part E Regulations and the enhanced CSH (Code for Sustainable Homes) requirements* with the minimum of components. *+3dB and +5dB over Part E for separating elements (Code for Sustainable Homes Technical Guide – November 2010)

FIRE:

With occupants of all ages, most often present at night while asleep, a fire resistant design is essential. Multi-storey buildings and their escape routes present even greater fire resistance needs, as stipulated by Building Regulations Part B – Fire Safety. GTEC Partitions and GTEC Ceilings achieve a full range of fire resistance using minimal components for multi-storey apartments, dense housing developments and detached houses. Robust and proven detailing enables design flexibility and economic construction.

SUSTAINABILITY:

Dwellings are responsible for up to 30% of national carbon emissions through their construction and use. Huge changes to the Building Regulations, as well as the Code for Sustainable Homes (CSH), have been implemented to reduce these carbon emissions representing a major shift in construction methods. The use of GTEC Systems can earn CSH credits in a variety of ways – for more details see the Sustainability section on pages 336-340. GTEC Systems are made up of fully recyclable components with gypsum plasterboard being 100% re-usable in a closed loop process. Recent product innovations use minimal components to achieve technical performances, limiting material usage and waste. All GTEC Lining systems can provide insulation to enhance the thermal performance of external walls. These include the GTEC Thermal Boards range; thermally laminated plasterboards which are recommended by Approved Document L1B to achieve thermal upgrades in renovation projects.

INVENTED BY SINIAT

SYSTEM SOLUTIONS Each of our three unique boards elevates the final layer of the partition, ceiling or lining, to previously unknown levels of standard plasterboard construction. These capabilities drive a different ethos in specifying drywall systems – the basic demands of acoustics and fire are always achievable and the focus can now switch to these extra benefits. Good design means every space has its own needs and tuning boards to best suit these demands is made possible. FROM TWO BOARDS TO ONE

OPPOSING NEEDS

For many performance requirements the board configuration can be improved with Siniat products, from two layers of a lower spec board to just one layer of a board such as GTEC Megadeco or LaDura. This can drastically reduce the number of boards needed on site. One high performance technical board can often do the job of two standard boards. Installation time is reduced without having to fix multiple layers, there is less waste as material volumes are reduced and the whole project becomes simpler to specify and manage.

Great architectural design will not always place identical rooms on opposite sides of a partition. With Siniat systems this problem is solved with hybrid system make-ups giving different finishing performance on each side of the partition. For example, a partition between a shower room and a corridor in a school could use GTEC Aqua Board on one side and GTEC LaDura for the corridor side. The lower of the two corresponding performance values for sound or fire being would be used unless the system has been tested in a hybrid make-up.

SYSTEM PERFORMANCE

SYSTEM PERFORMANCE FIRE Gypsum is a naturally fire resistant material, locking in water which will be released during a fire. This water controls the temperature allowing plasterboard systems to survive a fire for substantial lengths of time. The requirement for fire protection in a project is driven by the Building Regulations, fire strategy and any high risk equipment or activity in a building. The ratings in this manual represent the minimum passive fire protection that can be expected in a fire and can be used to show compliance with the current Building Regulations in the UK and Northern Ireland. The fire ratings of the systems are determined by testing and assessment to British and European standards. In the UK the BS 476 series of test standards and BS EN 1361, 1362, 1363 standards are used to establish the fire resistance of building elements such as walls and ceilings. A different temperature monitoring method is adopted in the European test methods and the results obtained are not the same as the British Standard results; both results are declared in this manual where possible. The tests are carried out in 3m x 3m aperture furnaces which simulate the most intensive period in a fire. The results of these tests are expressed in terms of integrity, insulation and loadbearing capacity (where applicable).

SYSTEM PERFORMANCE

ACOUSTICS Control of sound in buildings is essential for comfort. Plasterboard systems can assist with acoustic requirements in two ways, through sound insulation and sound absorption. Sound insulation is principally driven by the surface mass of a building element. As a thin, dense material plasterboard can be used to provide adaptable solutions for minimising sound transmission. Plasterboards generally reflect sound, however, perforated boards enable effective sound absorbing systems to be built. For residential construction the Building Regulations contain minimum values for sound transmission between rooms and absorption within communal areas. For many other projects acoustics are beyond the remit of building regulations. It is essential to consider the noise tolerance and noise output of neighbouring spaces to select the right levels of sound insulation for the separating element, consultation with acousticians is recommended. The sound insulation values quoted in this manual use consistent laboratory testing to allow system comparison. Elements are placed in an aperture between spaces with the reduction in sound pressure between the two spaces being recorded; this testing is carried out to BS EN ISO 140 and BS EN ISO 717 standards. The result is the Weighted Sound Reduction Index (Rw) measured in decibels (dB) with higher values offering better insulation. Site testing uses a different measurement method of Standardised Level Difference (DnT,w) where values around 7dB lower than laboratory tests can be expected. It is critical to seal all air paths, avoid routes for sound to ‘flank’ the element and build to high standards to achieve

Sound absorption is calculated through laboratory testing to European and ISO standards where a component is located in a space with known reverberation – the resulting reduction in reverberation time gives a coefficient of sound absorption. This co-efficient varies between 0 and 1 with higher values representing greater absorption per square metre.

SYSTEM PERFORMANCE

STRUCTURE A major advantage of plasterboard systems is their low mass to height/span ratio, this enables tall partitions and wide spans to be created without imposing high loads on structures supporting the system. As a lightweight system overall robustness must be considered and by using the correct framework and board combinations extremely tough partitions, ceilings and linings can be built. The maximum height of a partition is determined from its ability to resist a uniformly distributed lateral pressure, taken as 0.2kN/m2 for most internal applications, and limiting the resulting deflection to height/240. Greater lateral pressures and other imposed loads are possible and depend on the layout adopted. The ‘Strength’ criterion in the System Performance Tables is determined according to the test methods and criteria given in BS 5234-2. There are four grades in the standard, increasing in robustness from Light, Medium, Heavy to Severe Duty. In most projects the use of the lowest duty grade will result in walls which are too flexible for the expectations of users and are not generally recommended.

Based on extensive testing and calculations the height values shown in this manual are the maximum that the system can safely satisfy when fully built. Care must be taken during construction to ensure that the construction sequence does not undermine structural strength and construction loads are not applied to the systems. The ceiling systems in this publication will not support imposed loads in addition to those given in the appropriate sections. Fixings to structural elements must be determined by suitably qualified professionals and are not the responsibility of Siniat.

SYSTEM PERFORMANCE

THERMAL Plasterboard is not a low conductivity material but can be combined easily with different types of thermal insulation to create systems or products (such as GTEC Thermal Boards) which offer excellent thermal insulation properties. Plasterboard systems can contribute to construction with the most thermally efficient U-values satisfying new build or renovation building regulation requirements. Plasterboard is dimensionally stable and can be ideal as the air-tightness envelope in a building, with projects typically achieving 3m3/hr/m2 @ 50Pa, exceeding the building regulation requirement. The stability of plasterboard systems also allows construction independent of the substrate to prevent thermal bridging.

this manual so it is often possible to achieve improved U-values by changing the quality and quantity of insulation, contact Technical Enquiryline for further information.

The U-values quoted in the system performance tables can be used in SAP and SBEM calculations either as part of an external element or as the whole element where no other material is involved. For thermal upgrades to existing dwellings the default U-values for construction types and ages found in RdSAP 2009 have been used to indicate a resulting U-value with GTEC products and systems. Only a select range of systems configurations can be shown in

TYPICAL U-VALUES FOR PART L 2010

U-values are calculated, following the conventions of BR 443, using specialist calculation software, from conductivity values in international standards or manufacturers’ information. In product reference tables the quoted conductivity values (λ) W/mK for the materials in specific products have been used to calculate the thermal resistance (R) mK/W for that product. The GTEC range does not include independent insulation and therefore U-values should always be checked against manufacturer’s data for the actual insulation used in construction.

PARTITION PERFORMANCE NOTES Performance values are for imperforate, jointed systems using Siniat GTEC components (metal studs and tracks, boards, metal accessories, screws and finishing systems) and specified insulation quilt material (type, thickness and density) and installed to Siniat specification and installation guides. Any alterations may impair the quoted performance. Contact Technical Enquiryline for further system configurations and their resulting performances. All maximum heights are based on a maximum partition deflection limit of height/240 at the stated duty ratings under a uniform lateral pressure of 0.2 kN/m2 and can be increased using thicker gauge studs. Maximum height can be increased by 0.3m for single layer boarding and by 0.6m for double layer boarding when studs centres are reduced to 400mm. The maximum partition height may vary from the quoted values if the fire resistance of the system is specified according to BS EN 1364-1. Insulation shown may be replaced with thicker and/or heavier quilt material without impairing the quoted performances.

GTEC® C STUD PARTITION

®

GTEC C STUD PARTITION SYSTEMS GTEC Metal Stud Partitioning is an economical, friction-fit system for assembling internal partitions. The unique design of the components ensures high strength, easy installation and a higher performing alternative to traditional timber frame partitions. GTEC C Stud Partitions are constructed using a frame of GTEC U Track at the head and base with GTEC C Studs for vertical framing elements. A range of GTEC C Stud and U Track widths allow varying partition depth, enhancing fire resistance, sound insulation and maximum heights. For individual system performances, refer to the System Performance Tables on pages 22 to 44.

WHERE TO USE: GTEC C Stud Partitions create internal dividing walls within both domestic and commercial projects.

FEATURES

BENEFITS

GTEC® ACOUSTIC STUD PARTITION

®

GTEC ACOUSTIC STUD PARTITION SYSTEMS The GTEC Acoustic Stud is an alternative to 70mm, 90mm and 146mm GTEC C Studs, where higher levels of acoustic performance are needed from a partition. With a unique profile design, the engineered slots create a spring section, resulting in less acoustic energy being transmitted through the stud and sound is absorbed within the partition. Compatibility with the GTEC C Stud system and all GTEC Boards allows a range of partition performances within identical footprints. For individual system performances, refer to the System Performance Tables on pages 22 to 44.

WHERE TO USE: GTEC Acoustic Stud is an internal partition system for commercial and domestic applications requiring high acoustic performance levels.

Benefits from all key features as detailed for GTEC C Stud, plus:

BENEFITS

Compatible with GTEC U Tracks

Only requires one change in component in a specification and on site Partition types can be mixed on site

GTEC® ACOUSTIC HOMESPAN PARTITION

®

GTEC ACOUSTIC HOMESPAN PARTITION SYSTEMS The GTEC Acoustic Homespan system is a lightweight partition specifically designed to meet Building Regulation Part E where 40RwdB is required for internal partitions in dwellings. This performance is achieved using 44mm and 50mm GTEC Acoustic Homespan Studs and Tracks and GTEC Acoustic Homespan Board without the need to install insulation to achieve a 40RwdB rating. The narrow stud width and specially configured boards simplify specification and use the least material to achieve the demands of Part E.

WHERE TO USE: GTEC Acoustic Homespan is an internal partition for new-build domestic applications.

Benefits from all key features as detailed for GTEC C Stud, plus:

GTEC® RESILIENT BAR PARTITION

®

GTEC RESILIENT BAR PARTITION SYSTEMS GTEC Resilient Bar is a versatile component that can be used with a variety of partitions to provide improved acoustic performance. GTEC Resilient Bar decouples the plasterboard from the metal frame to reduce sound transmission with little increase in thickness. It is fixed across the flanges of GTEC C Stud and GTEC Board to provide a substrate for the plasterboard away from the metal framing. Refer to the System Performance Tables on pages 22 to 44 for full details. See the GTEC Timber Partitions section for details on using the GTEC Resilient Bar with timber construction.

WHERE TO USE: GTEC Resilient Bar is used with the GTEC C Stud Partition system in both domestic and commercial applications.

GTEC® TWIN FRAME PARTITION

®

GTEC TWIN FRAME PARTITION SYSTEMS Separating walls and divisions between noisy or noise sensitive rooms requires very high levels of sound insulation. The GTEC Twin Frame metal system is a dual layer C Stud Partition used where the highest fire and acoustic performance is required. GTEC Twin Frame Partitions are constructed from two metal frames in parallel, braced together with GTEC Acoustic V Brace and boarded on the external sides only. Varying cavity size options help optimise acoustic insulation and provide a service cavity. The GTEC Twin Frame system is a lightweight, flexible option compared to traditional masonry separating walls. Refer to the System Performance Tables on pages 22 to 45 for full performance details.

WHERE TO USE: GTEC Twin Frame systems are suitable for creating internal dividing walls in both domestic and commercial applications with increased performance and / or height requirements. The highest performing GTEC Twin Frame partitions are commonly used in cinemas, theatres and schools.

Benefits from all key features as detailed for GTEC C Stud, plus:

GTEC® TIMBER PARTITION

®

GTEC TIMBER PARTITION SYSTEMS In timber frame construction or where traditional methods dominate, a timber partition may be the preferred construction method. GTEC Timber Partitions use timber studs and plates in place of metal framing with GTEC Board screw fixed to complete the partition. Refer to the System Performance Tables on pages 47 to 49 for full details. Separating walls can also be constructed with double layers of GTEC Board and twin timber frames built in parallel to create a separating cavity. Insulation is applied in between for further sound reduction.

WHERE TO USE: GTEC Timber Partitions are used to create internal and separating partitions within domestic applications.

GTEC® SUSPENDED MF CEILING

®

GTEC SUSPENDED MF CEILING SYSTEMS The GTEC Suspended MF Ceilings are used to create ‘false ceilings’ which house services between the ceiling and soffit. The large voids created also improve acoustic, fire and thermal performance. GTEC Suspended MF Ceilings are formed from a series of GTEC Primary Channels hung from the soffit. Attached to these channels are GTEC Ceiling Channels, slotted into GTEC Edge Channel to form the frame. GTEC Board is fixed to the MF frame to complete the system. Refer to the System Performance Tables on pages 133 to 136 for full details.

WHERE TO USE: GTEC Suspended MF Ceilings are used for commercial applications where services are required below the soffit. For ceilings with enhanced fire and acoustic performance in commercial and residential applications.

FEATURES

BENEFITS

GTEC® PREGYBEL MF CEILING

®

GTEC PREGYBEL MF CEILING SYSTEMS The GTEC Pregybel MF Ceiling system is used for creating sound absorbing ceilings to control sound reflection in larger spaces, creating a more comfortable level of sound and improved audibility. GTEC Pregybel MF Ceilings combine the easy to install advantages of the GTEC Suspended MF Ceiling with the sound absorption capability of GTEC Pregybel Board. Using frame components from the GTEC Suspended MF system enables flexible design and specification. GTEC Pregybel board is perforated in a range of patterns for attractive designs and reduction in the reflective surface of the board to limit echo or reverberation. Refer to the System Performance Tables on pages 131 to 132 for full performance details.

WHERE TO USE: GTEC Pregybel MF ceilings are used in commercial applications where large, hard-surfaced and uninterrupted spaces would otherwise suffer from echoing. GTEC Pregybel MF ceilings are also required for corridors and stairwells in residential blocks to reduce sound travel through the building.

FEATURES

BENEFITS

Variable cavity depth

Cavity size can be optimised for service and insulation requirements Up to Class B acoustic absorption

Utilises GTEC Suspended MF framing

GTEC® DRYLINER CEILING

®

GTEC DRYLINER CEILING SYSTEMS The GTEC Dryliner Ceiling system is a simple, quick and cost-effective method for constructing a true, flat ceiling, even when connecting to uneven joists or concrete soffits. It also creates a small cavity to accommodate services. GTEC Dryliner ceilings are made from GTEC Dryliner Brackets fixed to the soffit or joists, with GTEC Dryliner Channels secured to them. The channels provide a strong, level substrate for fixing the plasterboard. GTEC Dryliner Brackets are available for a range of cavity depths up to 130mm. Fire rating and acoustic performance can be enhanced by the selection of appropriate GTEC Boards. Refer to the System Performance Tables on page 127 for full details.

WHERE TO USE: GTEC Dryliner Ceilings are used for both domestic and commercial applications for either new build or renovation projects.

GTEC® ACOUSTIC FLOOR

®

GTEC ACOUSTIC FLOOR SYSTEMS Load bearing timber floors separating dwellings or other spaces have limited sound reduction properties. The GTEC Acoustic Floor, ‘floating floor’ system improves the acoustic performance of these floors with minimal additional depth. The system is installed in a two stage process. GTEC Acoustic Clips temporarily support GTEC Board mounted on GTEC Metal Angle between the joists, until the final floorboard layers are fixed to the plasterboard. The only contact between the board and structure is through GTEC Resilient Tape. The GTEC Acoustic Floor system also enables fire protection for existing, hard to renovate, decorative ceilings by applying GTEC Fire Board from above. Refer to the System Performance Tables on page 137 for full details.

WHERE TO USE: GTEC Acoustic Floors are used for domestic renovation and conversion projects or new build.

GTEC® CONTOUR LINING

®

GTEC CONTOUR LINING SYSTEMS The GTEC Contour Lining system is a simple and fast means of renovating flat walls which simply need a new, consistently smooth finish e.g. tiled or plastered walls which have become scuffed or chipped. The system uses GTEC Wall Lining Adhesive to directly attach light and strong GTEC Contour Board to the substrate. It provides a smooth surface by boarding over existing finishes but will not correct substrates which are out of plumb. Once complete, the system provides a smooth and easy to finish plasterboard surface in the minimum thickness.

WHERE TO USE: GTEC Contour Board Lining system is suitable for use over existing wall finishes such as distressed tiled walls.

FEATURES

GTEC® SHALLOW WALL LINING

®

GTEC SHALLOW WALL LINING SYSTEMS The GTEC Shallow Wall Lining system is an alternative to the GTEC Direct Bond Lining system. It provides a mechanical fix for boards which are unsuitable for use with GTEC Universal Bonding Compound. It can also create a fully mechanically fixed option where the substrate cannot be bonded, such as some concrete walls. The system uses GTEC Universal Bonding Compound to attach GTEC Shallow Wall Channels to the substrate providing a fixing surface for GTEC Boards. When bonded, it can correct minor surface irregularities through minimal levelling adjustment of the shallow channel before the dabs have cured. Alternatively, the GTEC Shallow Wall Channels can be fixed directly into the substrate.

WHERE TO USE: The GTEC Shallow Wall Lining system is suitable for most project types and masonry substrates.

GTEC® DRYLINER LINING

®

GTEC DRYLINER LINING SYSTEMS The GTEC Dryliner Lining system is a fully dry, light frame, drylining system. The cavity created behind the boards allows for heavier services and sound or thermal insulation. For stable, high performance drylining, the system uses GTEC Dryliner Brackets fixed to the substrate to support a frame of GTEC Dryliner Channel and Tracks. Once complete, the GTEC Dryliner Lining system provides a clean, flat and easy to finish plasterboard surface with superior technical performance than shallow lining systems.

WHERE TO USE: The GTEC Dryliner Lining system is ideal for most stable substrates where continuous cavities behind boards of up to 130mm are required and/or where high levels of substrate correction are needed.

GTEC® INDEPENDENT WALL LINING

®

GTEC INDEPENDENT WALL LINING SYSTEMS Based on the GTEC C Stud Partition system, the GTEC Independent Wall Lining system is a fully dry, light frame, drylining system. It is completely separated from the underlying substrate. The GTEC Independent Wall Lining system combines GTEC Boards with GTEC I or C Studs fixed into GTEC U Tracks. The cavity created behind the boards can be of any depth. This allows for heavy services, ducting, and insulation. Once complete, the GTEC Independent Wall Lining system provides a clean, flat and easy to finish plasterboard surface, offering the highest technical performances.

WHERE TO USE: Ideal for commercial projects where deep continuous cavities behind boards are needed to correct or isolate substrates and accommodate services. Particularly suited to substrates which may not be suitable for direct fixing, e.g. metal cladding and other modern methods of construction.

GTEC® SHAFTWALL

®

GTEC SHAFTWALL SYSTEMS The GTEC Shaftwall Fire Protection system protects shafts and voids in multi-storey buildings with a rapid installation system preventing continuous routes for the spread of fire. The system uses a non-symmetrical board assembly for full installation from one side of the shaft, allowing construction in tight spaces. The frame features friction fit channels to receive GTEC Fire Core Board and a fixing flange for the installation of GTEC Fire, Megadeco or Universal Boards ready to finish on the room side. The shaft side can also be decoratively finished using GTEC Shaftwall Stairwell systems, this is commonly used in stairwells. GTEC Shaftwall Fire Protection can also be used horizontally to protect the underside of ductwork or provide a ‘lid’ to a shaft. In horizontal applications, further boards may be needed to achieve fire performances. Refer to the System Performance Tables on pages 244 to 249 for full details.

WHERE TO USE: GTEC Shaftwall Systems are used to protect voids in commercial or public multi-storey buildings and is suitable for most construction types.

GTEC® ENCASEMENT

®

GTEC ENCASEMENT SYSTEMS The GTEC Encasement Fire Protection system provides high levels of fire resistance to structural I-section columns and beams, delaying the loss of strength in steel which occurs at temperatures over 550°C. The system uses push-fit GTEC CB Clips to secure GTEC Edge Channel to the steel. GTEC Fire Core Boards, Fire Boards, and other high performance boards as detailed in the performance tables, are fixed to the edge channel to protect columns and beams. Excellent fire performance is achieved by holding the boards off the columns on a strong metal frame.

WHERE TO USE: The system is used in commercial multi-storey construction to ensure structural safety during fire. The range of impact resistant boards compatible with the system enables use in high traffic areas.

FINISHING GTEC Taping and Jointing provides a finish to joints between GTEC boards creating a continuous, fire resistant and easy to decorate surface. Skimming can achieve similar results but is a more labour and time intensive method. Tiling GTEC moisture and wet area GTEC boards can achieve exceptionally high levels of water resistance. GTEC Cove is a decorative gypsum element used to finish the junction between partition and ceiling.

GTEC® TAPING AND JOINTING

®

GTEC TAPING AND JOINTING GTEC drywall systems require taping and jointing to complete the wall surface, reinforce joints to prevent cracking, and ensure fire and sound performances are achieved. GTEC Taping and Jointing products use limited combustibility, gypsum and limestone based compounds which secure the fire rating of the system. These are reinforced with paper tape or corner beads to create a smooth, durable surface, ready for decoration. Two and three stage processes are available using the correct GTEC Finish products to provide options on site and different setting times. Water resistant compounds and finishing accessories are available for GTEC Aqua Board. The GTEC Deco compound range complements the use of GTEC Megadeco for direct decoration.

WHERE TO USE: Taping and jointing are suitable for large surface areas where speed and ease of application can greatly reduce installation cost and drying time.

GTEC® TAPING AND JOINTING

SYSTEM GUIDANCE COMPOUND SELECTION Joint compound selection is largely a matter of site preference, depending on weather conditions, time and equipment. GTEC Compounds can be combined in numerous permutations each offering a high quality surface finish. However, GTEC Aqua Board and

GTEC Megadeco require specific compounds to suit their unique facers. Taping and jointing is conducted in three main stages: Bedding; Second Coat; and Finishing Coat.

TWO STAGE PROCESS

1

THREE STAGE PROCESS BEDDING Tape or bead is bedded into the compound and taper filled out

SECOND COAT The taper is re-filled with compound where required

1 2

FINISHING COAT

2

Final compound layer is applied and sanded for a smooth finish

3

COMPOUND TYPES All compounds are suitable for Bedding and Second Coat, however, setting and hybrid compounds reduce overall time required. Setting and hybrid compounds must not be used over air-drying compounds. Only air-drying or hybrid compounds are suitable for the final finishing coat.

Air-drying and hybrid compounds are low shrinkage. Where low shrinkage compounds have been used in Bedding layer the Second Coat may not be required. The drying time of air-drying compounds is dependent on climatic conditions and layer thickness. Drying takes approximately 24 hours but may be extended by adverse conditions.
